Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously The present invention is not limited, structure that those skilled in the art are made according to these embodiments, method or functionally Transformation is included within the scope of protection of the present invention.
One embodiment of the invention provides a kind of hot mouth component 100, as shown in Figure 1, hot mouth component 100 include hot mouth 1 and It is arranged in sharp-tongued the 2 of 1 end of hot mouth, through there is runner 11, sharp-tongued 2 end sleeve is equipped with compressing member 3 for hot mouth 1 and sharp-tongued 2 inside;Note The liquid Material of modeling flows to sharp-tongued 2 by runner 11 from hot mouth 1, then is flowed into compressing member 3 from sharp-tongued 2 end, compressing member 3 Cooperate with mold, is flowed into mold.
In the present embodiment, clearly to express described position and direction in the application, during hot mouth component 100 has Axis is directed toward the side in downstream by 11 upstream of hot flow path referring generally to the upstream and downstream direction of 100 runner 11 of hot mouth component along central axes To being defined as "lower", otherwise it is defined as "upper".
Specifically, hot mouth 1 is arranged sharp-tongued 2 above, the setting of compressing member 3 is below sharp-tongued 2, and the liquid Material of injection molding is from upper It flows downward;
Discharge port 21 is arranged in sharp-tongued 2 end, and the Material in sharp-tongued 2 is flowed out from discharge port 21, on the inside of compressing member 3 in setting Heat-insulating and sealing cap 4, the channel 41 of the inside setting perforation of heat-insulating and sealing cap 4, sharp-tongued 2 insertion channel are arranged in inner cavity 31 for chamber 31 In 41, heat-insulating and sealing cap 4 is spaced apart sharp-tongued 2 with compressing member 3, and the liquid Material in inner cavity 31 will not enter heat-insulating and sealing Position where cap 4;The inner wall of compressing member 3 and sharp-tongued 2 outer wall are closely affixed with heat-insulating and sealing cap 4, i.e. heat-insulating and sealing cap 4 Sharp-tongued 2 and compressing member 3 are sealed, block liquid Material which and unapproachable position by heat-insulating and sealing cap 4 from entering, such as Shown in Fig. 2 or Fig. 3, liquid Material is sprayed from the discharge port 21 of sharp-tongued 2 end, since heat-insulating and sealing cap 4 has blocked passage portion 41, so that liquid Material is cannot be introduced into the portion of top of heat-insulating and sealing cap 4.
Further, in this embodiment discharge port 21 be arranged it is multiple, multiple discharge ports 21 to multiple directions discharge, make Material Flow out it is more uniform, more specifically, in the present embodiment discharge port 21 be arranged 3, spray liquid Material along 3 directions, and mix It closes in the inner cavity 31 of compressing member 3, to be uniformly mixed, then flows to mold from the material feeding passage 4132 of compressing member 3;
Further, guiding port 42 is arranged in the end of the discharging direction in channel 41, and guiding port 42 is for spraying multiple directions Material out continues to flow in a certain direction, and guiding port 42 does not stop discharge port 21 and material feeding passage 4132, is conducive to avoid Guiding port 42 flows Material to form resistance and generation dead angle;
Further, the internal diameter of guiding port 42 becomes larger along discharging direction, edge and the inner cavity 31 of guiding port 42 Inner wall offsets, and in the marginal position of guiding port 42, the internal diameter of guiding port 42 at this time is maximum, the side of the guiding port 42 of maximum inner diameter Edge point and 31 inner wall of inner cavity of compressing member 3 offset, and liquid Material is made not enter the upper of heat-insulating and sealing cap 4 from the position Side;
Further, the inner wall of guiding port 42 be the conical surface, multiple discharge ports 21 be inscribed within guiding port 42 inner wall or The extension of its conical surface, as shown in Fig. 2, so that dead angle position is not present, cooling Material is not when meeting the geometry site It can be set in dead angle and the injection molding of next time is caused to hinder, the Material sprayed at this time from discharge port 21, along in guiding port 42 Wall sprays.
The inner wall of inner cavity 31, and/or, the position that sharp-tongued 2 outer wall is contacted with heat-insulating and sealing cap 4 is smooth song Face, it is even closer that smooth curved surface cooperates heat-insulating and sealing cap 4 directly with compressing member 3 and sharp-tongued 2, prevents cooperation not tight enough Close and smooth surface facilitates the flowing of fluid, and Material is further prevented to enter 4 top of heat-insulating and sealing cap.
Further, the cavity 33 for detecting whether flash is formed between the top of heat-insulating and sealing cap 4 and compressing member 3, The cavity 33 is set for detecting the airtight quality of heat-insulating and sealing cap 4, when there is defective material to enter in cavity 33, that is, can determine whether every The airtight quality for heating seal cap 4 is bad, conveniently makes improvement.
Further, heat-insulating and sealing cap 4 is in the state for being compacted part 3 and sharp-tongued 2 compression;When heat-insulating and sealing cap 4 is pressed When tight, the effect of power keeps sealing state more preferable, on the one hand ensure compressing member 3 with after sharp-tongued 2 assemble, inner cavity between the two 31 will not allow heat-insulating and sealing cap 4 everywhere in the state of clearance fit, on the other hand, when compressing member 3 and sharp-tongued 2 assembles, be formed Certain pretightning force makes to support in inner cavity 31 at heat-insulating and sealing cap 4, guarantee and the compression shape between compressing member 3 and sharp-tongued 2 State.
Further, one embodiment of the application also provides a kind of 11 system of hot flow path, and 11 system of hot flow path includes above-mentioned Hot mouth component 100.
Compared with prior art, the present embodiment has the advantages that
(1) the hot mouth component 100 avoids internal excessive material residual, to accelerate cooling velocity, avoids wire drawing Phenomenon avoids clout and enters between sharp-tongued 2 and compressing member 3, avoid clout and remain in additionally, due to reasonable in internal structure Inside gradually turns yellow, and enters the problems in product so as to avoid the clout of yellowing, improves product quality;
(2) by the way that heat-insulating and sealing cap 4 to be arranged to certain shape, heat-insulating and sealing cap 4 is made to be conducive to Material in sharp-tongued 2 Injection, and avoid inside and dead angle occur;
(3) by the way that the shape of sharp-tongued 2 and compressing member 3 is made improvement, and heat-insulating and sealing cap 4 is made by the effect of power Sealing performance further increases.
Illustrating only for feasible embodiment of the invention is described in detail in those listed above, they are simultaneously It is non-to limit the scope of the invention, it is all without departing from equivalent implementations made by technical spirit of the present invention or change should all It is included within protection scope of the present invention.
